| Abstract | ||
| Objective: The objective was to evaluate the effects of varying grades of insect-formulated feeds (IFF) on finishing-phase performance and nutrient retention of caged Cobb broilers. Materials and Methods: Cobb broilers (n=1050) were randomly assigned 50 per treatment in tripled replicates to African palm weevil (APW), housefly maggot (HFL) and Cockroach (CKR) formulated meals for six weeks. Feed meals were formulated from larval stages of APW, HFL and adult CKR in single and combined forms, and commercial hybrid feed served as control. Birds were raised in an experimental animal house dimensioned 21.34-meter length by 3.05-meter breadth and divided into seven squared compartments. These seven compartments were further partitioned into three compartments each using wood, ply boards and net gauze which served as the three replicates for the experiment. Feeds and water were served ad libitum and feeding was done twice daily. Weekly readings of body length, weight, breast width, feed efficiency and nutrient retention analysis were done using fecal samples.Results and Discussion: Performance increased weekly and was highest in broilers fed African palm weevil meals (p< 0.05). Nutrient retention equally increased (p< 0.0001). The retention of dry matter, crude protein and calcium, ether extract, crude ash and phosphorus increased in housefly and African palm weevil and commercial hybrid feed respectively. Implications and Applications: Using these insects can result in improved performance and greater nutrient retention; however, an increased number of weeks is required. A formulated feed of African palm weevils could be adopted as a viable alternative for industrialized production. | ||
